1-Naphthalenesulfonic acid Chemical Properties,Uses,Production
Chemical Properties
grey fine crystalline powder
Uses
1-Naphthalenesulfonic acid was used as template molecule to prepare new non-covalent molecularly imprinted polymer for solid-phase extraction of naphthalene sulfonates.
Definition
ChEBI: Naphthalene-1-sulfonic acid is a naphthalenesulfonic acid.
General Description
Mechanism of metabolism of 1-naphthalenesulfonic acid by green algae Scenedesmus obliquus has been investigated.
Synthesis
Using o-nitrobenzene as a solvent, naphthalene, chlorosulfonic acid, and o-nitrobenzene were mixed in a molar ratio of 1:1.1:3, and sulfonation was carried out at 0-5℃ to directly obtain 1-naphthalenesulfonic acid with a purity of approximately 97%.
Purification Methods
Crystallise the acid from conc HCl and twice from H2O. The S-benzylisothiuronium salt has m 137o (from aqueous EtOH). [Beilstein 11 H 155, 11 III 383, 11 IV 521.]
